My 2005 Nissan Altima keeps giving PO302 code. I've changed spark plug, coil and harness connector. Whenever I change something, the problem goes away for about a week or two, then returns. WTF!

Do you
have the same problem?

Could be compression, vacuum leak, which is common on this model, faulty injector or wiring.

The vacuum leak is from the intake manifold gasket.
